直肠癌初期症状有哪些?(照片)
<p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;">直肠癌发病<span style="color: black;">初期</span>会<span style="color: black;">显现</span><span style="color: black;">有些</span>症状,<span style="color: black;">由于</span>直肠在消化道的末端,<span style="color: black;">病人</span>会<span style="color: black;">显现</span>便血、肛门的异物感和下坠感,<span style="color: black;">乃至</span>会<span style="color: black;">显现</span>“里急后重”,<span style="color: black;">便是</span>总想去排便,但又排不出来。直肠癌的便血和痔疮的<span style="color: black;">流血</span>还是有所不同的,痔疮是鲜红色的血便;直肠癌除了血便之外还伴有粘液,这种粘液<span style="color: black;">重点</span>是肿瘤的破溃<span style="color: black;">导致</span>的。<span style="color: black;">那样</span>;直肠癌<span style="color: black;">初期</span>症状有<span style="color: black;">那些</span>?</p>
<p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;">1、症状一:便血</p>
<p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;">便血是直肠癌最<span style="color: black;">平常</span>的症状,但很容易被误认为是痔疮而耽误治疗。直肠癌<span style="color: black;">导致</span>的便血多为红色或暗红色,可<span style="color: black;">显现</span>脓血便,有时会伴有血块或坏死组织。<span style="color: black;">非常多</span><span style="color: black;">病人</span>在<span style="color: black;">无</span><span style="color: black;">显著</span>诱因<span style="color: black;">显现</span>便血、肛门异物感后,<span style="color: black;">常常</span>会认为是痔疮<span style="color: black;">爆发</span><span style="color: black;">导致</span>,<span style="color: black;">忽略</span>了可能是癌变的<span style="color: black;">状况</span>。</p>

<p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;">2、症状二:大便习惯改变</p>
<p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;">排便习惯的改变<span style="color: black;">亦</span>是直肠癌的<span style="color: black;">平常</span>症状之一。<span style="color: black;">因为</span>癌症肿块及其分泌物会对肠道<span style="color: black;">导致</span>刺激,令便意频频,排便不尽感。晨起腹泻的<span style="color: black;">状况</span>会<span style="color: black;">增加</span>,<span style="color: black;">乃至</span>影响晚间的入睡,改变了往日大便习惯。</p>
<p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;">3、症状三:肠道狭窄及梗阻现象</p>
<p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;">随着肿瘤增大,很容易<span style="color: black;">导致</span>梗阻、直肠占位的现象。直肠壶腹部癌,因<span style="color: black;">大都是</span>溃疡型,直甩壶腹部较宽广,估计约1~2年<span style="color: black;">上下</span>才<span style="color: black;">导致</span>狭窄梗阻,大便形成变细,排便困难,便秘,<span style="color: black;">导致</span>腹部不适,气胀及<span style="color: black;">病痛</span>。<span style="color: black;">因为</span>粪便堆积,在梗阻上段乙结肠部位,有时在左下腹部,可扪及条索状肿块。</p>

<p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;">4、症状四:肛门<span style="color: black;">病痛</span>及肛门失禁</p>
<p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;">结直肠癌<span style="color: black;">初期</span>并<span style="color: black;">没</span>特异的<span style="color: black;">有些</span>表现,<span style="color: black;">因此</span><span style="color: black;">非常多</span>人会忽略掉。<span style="color: black;">因为</span>结直肠癌会便血,以至于有些人会把结直肠癌误认为是痔疮。结直肠癌划分得比较<span style="color: black;">仔细</span>,<span style="color: black;">包含</span>结肠和直肠。其中结肠又分为左半结肠和右半结肠。</p>
<div style="color: black; text-align: left; margin-bottom: 10px;"><img src="https://pic1.zhimg.com/80/v2-f4ea59621efec2489b0565f188888584_720w.webp" style="width: 50%; margin-bottom: 20px;"></div>
<p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;">结肠癌的症状相<span style="color: black;">针对</span>直肠癌<span style="color: black;">来讲</span>就比较隐秘,尤其是右半结肠癌离消化道末端距离较远,便血在肠道里被稀释以后颜色会和粪便<span style="color: black;">一块</span>,变黑变暗,<span style="color: black;">病人</span>会<span style="color: black;">显现</span>贫血和腹痛症状,<span style="color: black;">因此</span><span style="color: black;">非常多</span>人会忽略右半结肠癌。</p>
<p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;">总体而言结直肠癌<span style="color: black;">无</span>特异的表现,结直肠癌的可怕之处<span style="color: black;">便是</span>当<span style="color: black;">病人</span><span style="color: black;">显现</span><span style="color: black;">显著</span>的症状时<span style="color: black;">已然</span>不是<span style="color: black;">初期</span>了,<span style="color: black;">因此</span>变相的提出了<span style="color: black;">初期</span>体检<span style="color: black;">初期</span><span style="color: black;">发掘</span>的<span style="color: black;">要紧</span>性。</p>
